Reflux pharyngitis can not be self-tested, only through the typical symptoms of reflux pharyngitis to make a preliminary judgment, if the diagnosis needs to go to the hospital to improve the gastroscopy and other related examinations. The diagnosis of reflux pharyngitis needs to be based on the patient’s detailed medical history, typical symptoms of reflux pharyngitis, combined with physical examination, pharyngoscopy, gastroscopy and other laboratory tests to make a clear diagnosis. Chronic pharyngolaryngitis, gastroesophageal reflux and other diseases have similar symptoms with reflux pharyngitis, and differential diagnosis is also needed. Therefore, reflux pharyngitis cannot be self-tested. Reflux pharyngitis refers to the reflux of the contents of the stomach into the pharynx causing damage to the mucosal tissues of the pharynx, which can be manifested by symptoms such as sore throat, hoarseness, and a foreign body sensation in the pharynx. If you suspect that you are reflux pharyngitis, patients should go to the hospital in time to improve the relevant examination and active treatment, so as not to delay the condition.
